Solar PV mounting rails play a key role in mounting and supporting photovoltaic modules as an important part of a solar power system. In this article, we will introduce the functions of solar PV racking rails and their applications in solar power systems to better understand the importance of the rails.

I. Functions of solar photovoltaic mounting rails

l Supporting and securing PV modules: Solar racking rails are able to carry and support PV modules so that they are securely mounted in the desired location, ensuring that they receive the correct amount of sunlight radiation. The rails ensure accurate positioning of the PV panels and securely fasten the panels to the rails with bolts and other fixings to prevent displacement and damage under adverse weather conditions.

l Adjustment of tilt and orientation: The PV mounting rails are equipped with the function of adjusting the tilt and orientation, which can adjust the angle of the PV modules according to the position of the sun and seasonal changes in order to obtain the best light effect.

l Conductive and grounding function: As the load-bearing structure of the PV system, the racking rail must have the conductive and grounding function to ensure good electrical connection between the PV modules and between the system and the ground to ensure the flow of current and safe operation.

II. Application of solar mounting rails

l Roof mounting system: PV racking rails play a key role in roof mounting systems. By properly designing and installing racking rails, PV modules are mounted on the roof, where the tilt angle of the PV panels can be easily installed and adjusted, while ensuring the stability and safety of the system.

l Ground mounting system: For places where roof mounting is not possible, such as flat land, grass, etc., PV racking rails can be used for ground mounting systems. By fixing the racking rails on the ground, the PV modules are arranged on a large area to realize solar PV power generation.

l Solar power station: Large solar power stations usually use large area PV racking rail system to install a large number of PV modules on the racking to form PV arrays and centralized power generation. This application is widely used for commercial power supply and large-scale energy projects.

Choosing the right solar rail system is critical in the solar industry to ensure the safe, stable and efficient operation of your solar system.
